Minor BUG/oversight could possibly be classified as a feature request:

Carbonite updates its understanding of the reagent bank (evidently) only when you open the bank; unfortunately it doesn't deduct use of materials when crafting. For example, I had 200+ Burnished Leather in my bank, after making a Burnished Essense (150 B.L) the warehouse still thought I had over 200.

Feature requests would be:

Create an option to show/search all characters on all realms/factions - this is needed to find account bound items.
